HP-Plus® Silencer by Khrome Werks: a slip-on designed for the road and touring. This 4-1/2" silencer (outer diameter 11.5 cm) combines a dark look with the muscular sound characteristic of Khrome Werks, without the annoying highs. Designed for long stretches as well as strong accelerations, it provides acoustic presence and a finish that perfectly complements a touring Harley.
Ideal for road kings and road glides, this HP-Plus® enhances throttle response with an increase in torque and power at opening, while maintaining a deep and controlled tone. Perfect for the touring rider seeking an aggressive look and a sound that matches their engine.
